NOTEs:
1. NORMAL=typically the model normal based on historic runs rather than the measured normal from observation - hence trends rather than numbers are a better guide.
2. CFS2 seasonal anomalies are with respect to the lead dependent model climatology from the hindcast period (1999-2010) without any adjustment - a very warm decade!.
3. UKMET The hindcast period used for model normal is 1996 to 2009. 42-member ensemble seasonal forecast (120KM res over land) combining and bias correcting all forecast members available prior to issue.
4. CFS2 Weekly forecast anomalies are with respect to 1999-2010 hindcast climatology which was a warm period (SST 1982-2010) also mostly a wet period for Uk
compared to longer period stats.
